Misinformation research has a causality problem: lab experiments are limited; observational studies confounded. We used causal inference on 9.9M tweets, quantifying effects in the wild while blocking backdoor paths. Does misinfo get higher engagement? Are following discussions more emotional? 🧵

Very happy to update the {traktok} #rstats readme. After 1.5 years, you can finally search TikTok again without access to the Research API. It's slow and a bit clunky, but it works! Thanks, @michaelgoodier.bsky.social for the crucial hint!

If my network is anything to go by, the first EPSS conference is going to be a massive, enthusiastic success!

📢 The Fall Wave (Wave 33) of the GLES Panel is now in the field! From November 4 to November 17, we are conducting up to 13,000 interviews on a wide range of political topics 🗳️📊 Download the questionnaire (DE/EN) here: 👉 www.gesis.org/en/gles/over...

I strongly recommend @hugoreasoning.bsky.social's book "Not Born Yesterday" if you've been exposed to too much social psychology about irrationality in your youth. press.princeton.edu/books/hardco...

Ouch

Maybe your texts tell you to "BE A VOTER" like mine. It all started because of a PNAS paper that claimed that the noun form it increased voter turnout (relative to the verb form ) by 11 to 14 percentage points. It keeps not replicating, obviously. Most recently doi.org/10.1017/bpp....

I agree. Unfortunately, the OSF re-design isn't a big step forward. Took me quite a while today until I understood where to find the pre-registrations in my project

Final days to submit your abstract to the inaugural @epssnet.bsky.social conference! Deadline Nov 7 - epssnet.org/belfast-2026...

Really enjoyed this clear and concise presentation of the problem with studies that throw 10 different covariates into a multiple regression and interpret them causally. So obvious in hindsight that this is problematic, but I have definetly been guilty of this. bmjmedicine.bmj.com/content/4/1/...

Better get your paper submissions in for the @epssnet.bsky.social conference in June 2026, as the deadline is 7 November, and we have no intention of extended that (given the submission numbers)! epssnet.org/belfast-2026...

Dortmund stabil!

Happy to share that our paper on the ideological biases of international organizations is now out in the current issue of the AJPS (@ajpseditor.bsky.social): dx.doi.org/10.1111/ajps... @the-peio.bsky.social @mzesunimannheim.bsky.social @akentikelenis.bsky.social

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >

Check out or new article — published today in @poppublicsphere.bsky.social — where we discuss and provide guidelines for the construction and use of datasets. We draw on our lessons from three major data collection efforts on education policies and systems 👇

This week, we have @lorenzspreen.bsky.social visiting our lab. He presented his work on disinformation classification and toxicity in group discussions on Reddit. He also has a new CSS group, check it out: css-synosys.github.io

🆕 Latest article out @electoralstudies.bsky.social! Left parties' higher salience on cultural issues associated w/ higher support from working-class voters. Social democrats much more sensitive to different strategies, should pursue more left/salient economics www.sciencedirect.com/science/arti...

Very happy to announce the new Anthology for Computers and the Humanities! 🎉 Inspired by the wonderful ACL Anthology, this is an open, accessible, centralized repository for papers at different workshops, conferences, and related venues. All thanks to @taylor-arnold.bsky.social!

Interested in understanding #bias in #CSS? ✨Here's our Special Issue editorial in Communication Methods and Measures: "Critical, but constructive: defining, detecting, and addressing bias in Computational Social Science" 👉 doi.org/10.1080/1931... (with @bachl.bsky.social & Nathan TeBlunthuis)

We are finally out!! Thanks to my fantastic co-authors, the anonymous reviewers, and @thejop.bsky.social editorial team. Publishing my first registered report has been an incredibly instructive and rewarding experience 🤓 Much has been said about political incivility, but does it actually exist? 🤷‍♀️

Join us in 3 hours (at 17:00 Berlin time) to discuss replication problems of language models and recommendations for research! 🚨 for those from a different time zone: Germany already switched back clocks last weekend, so depending on where you are the time difference might be an hour off from usual

Thanks to the great help by @rstrauch.bsky.social, Gabriele Spilker and the Cluster of Excellence "The Politics of Inequality" @excinequality.bsky.social, version 5.0 of the "Mass Mobilization in Autocracies Database" (coverage until 2022) is now available at mmadatabase.org!

Who’s gonna pay @rpsychologist.com to make a mega tool converting all g*power analysis types to an interpretable web tool like this?

🚨 New piece out at @thejop.bsky.social w awesome @cvargiu.bsky.social & D Garzia If incivility means breaking norms, & norms are person- and context-dependent, *does incivility even exist*? In the stage-2 registered report we investigate what drives perceptions of incivility tinyurl.com/4h5u4y8y

🎉 @rpsychologist.com 's PowerLMM.js is the online statistics application of the year 2025 🎉 powerlmmjs.rpsychologist.com - Calculate power (etc) for multilevel models - Examine effects of dropout and other important parameters - Fast! (Instant results)

Tapping the sign:

My lab is looking for a Senior Scientist (= PostDoc with option of permanency)! We are looking for someone interested in doing cutting-edge computational social science + helping us with data & software engineering 🤓. See job ad for details jobs.uni-graz.at/en/jobs/7d14...

The key terms here are: 1) burdensome procedures 2)burdensome tools While the findings themselves are not public, let's take a closer look 🧵👇

A massive study on the effects of social class tested 35 hypotheses in 4 countries (N = 33,536) Only 50% of findings replicated Hypotheses based on differences between social class contexts in terms of constraints, uncertainty & status were supported: www.nature.com/articles/s41...

Moreover, I have recently been awarded an ERC starting grant towards the project GETGOV to work further on this, so expect more data on cabinet members in the future. I am currently hiring two PhDs and two postdocs: www.jobbnorge.no/en/available... www.jobbnorge.no/en/available...

🚨 out at @apsrjournal.bsky.social 🚨 ➡️ We ran a large media literacy experiment to fight misinformation ➡️ 13,500 students, 583 villages in Bihar, India ➡️Created custom misinfo curriculum of 4 months ➡️Partnered w the government to roll it out as an official course in classrooms hopeful findings👇🏽

Colleagues: What’s your favorite, accessible resource (reading, video, slide deck) to convince students that regression on observational data—even with many controls—is not often causal. (Quasi-)experimental designs are preferred for causal inference.

Next Wednesday (October 15, 17:00 Berlin time), we're kicking off next term's Speaker Series with a talk and package demo by Francisco Tomas-Valiente on "Uncertain Performance: How to Quantify Uncertainty and Draw Test Sets When Evaluating Classifiers". Paper and information on how to join ⬇️

We started @metaror.bsky.social MetaROR.org in part because of the absence of a journal that publishes metascience. But rather than a traditional journal, as metascientists we wanted to explore the next frontier - Publish, Review, Curate.

This is a highly interesting, timely and great initiative - a new diamond OA journal for #replication research! It is interdisciplinary, but #PolSci is specifically invited. Hence, if you or someone you know has an interesting replication paper, do not hesitate to submit!

ReplicationResearch.org is now open for submissions! Submit replications and reproductions from many different fields, as well as conceptual contributions. With diamond OA, open and citable peer review reports, and reproducibility checks, we push the boundaries of open and fair publishing.

💯 Academic social media was a game changer for scholars from traditionally less well-connected places.

JUST OUT: "Boundaries and Cleavages: Elements of a Cultural Sociology of Political Divides." OA: direct.mit.edu/ecps/article... It develops what the cultural sociology of group formation can contribute to research on political cleavages. (And why "Somewheres vs Anywheres" really doesn't cut it.)

The Academy of Sociology (Akademie für Soziologie, not on Bsky wut?) is offering a 1,500 Euro prize for the best #replication study in #sociology as25.sociology.uni-mainz.de #openscience 🧪

Great paper on the state of political science osf.io/preprints/os... by @guygrossman.bsky.social et. al. We have become more diverse, more quantitative, and more collaborative.

Really excited that after several years of working on it, revising, and getting lots of rejections, our paper (w/ Rune Stubager & Mads Thau) on citizens’ responses to group appeals is *finally* out @ejprjournal.bsky.social www.cambridge.org/core/journal... A 🧵 on our findings...

🧵 New publication: How do people feel about regulating #AI in election campaigns? 🧵 In a new article, @adrauc.bsky.social, @kunkakom.bsky.social, and I examine when and why people support stronger AI regulation in political competition. www.sciencedirect.com/science/arti... 👇

7 years ago Tim Cook told the European Parliament: “We're responsible for recognizing that the devices we make and platforms we build have real…lasting…even permanent effects on individuals and communities who use them We must never stop asking ourselves What kind of world do we want to live in?"

The Hertie School mourns the passing of Prof. Dr Dr h.c. Claus Offe, Professor Emeritus of Political Sociology, an extraordinary scholar, teacher and colleague. We extend our heartfelt condolences to his family, friends and all who had the privilege to know him.

RIP Claus Offe. He built his own monument in his work; here’s something great. www.hwiesenthal.de/publik/hw/2l...

Still confused about EPSA vs. EPSS? Which conference should you go to? Here is a link to clarify things: epssnet.org/uncategorize... TL;DR: "EPSA" community will be in Belfast. Same community, new organisation, bigger mission; slightly new name; and a very different foundation @epssnet.bsky.social

The—AI-related—stigmatization of the em dash makes it even harder to squeze my very German thoughts into english words.
